It should be understood that the specific embodiments described hereinare merely used to explain the present invention but are not intended tolimit the present invention.

Referring to FIG. 1 and FIG. 2, a fresh air assembly according to anembodiment of the present invention includes a housing 1, a cross-flowimpeller 2, evaporators 3, and an air deflector 4. The cross-flowimpeller 2, the evaporators 3, and the air deflector 4 are all disposedinside the housing 1. The evaporators 3 are disposed on one side of thecross-flow impeller 2 in a direction around the cross-flow impeller 2.Both ends of the air deflector 4 are connected to the housing 1 to forma first cavity 5. One end of the evaporators 3 is connected to thehousing 1 and the other end thereof is connected to the air deflector 4to form a second cavity 6, the second cavity 6 communicates with thefirst cavity 5, the evaporators 3 are enclosed with the air deflector 4to form a wind chamber 7, and the cross-flow impeller 2 is disposedinside the wind chamber 7. The housing 1 is provided with an air outlet17 and an air inlet 16, the air outlet 17 communicates with the windchamber 7, and the air inlet 16 communicates with the first cavity 5. Inthis embodiment, the second cavity 6 communicates with the wind chamber7 through the evaporators 3, and fresh air can flow into the windchamber 7 through the evaporators 3.

The working principle of the above-mentioned fresh air assembly is asfollows: The cross-flow impeller 2 rotates to form a negative pressurebetween the wind chamber 7 and the second cavity 6, so that theevaporators 3 draw the air in the second cavity 6 into the wind chamber7. Then, the air in the first cavity 5 flows into the second cavity 6 tosupplement the air volume in the second cavity 6. Finally, fresh airflows into the first cavity 5 from the air inlet 16 to supplement theair volume in the first cavity 5. In this way, an air flow passage isformed. Afterwards, fresh air enters the first cavity 5 from the airinlet 16, flows into the second cavity 6 from the first cavity 5, isdrawn into the wind chamber 7 by the evaporators 3, and is blown into aroom from the air outlet 17 under the action of the cross-flow impeller2. When the fresh air is drawn into the wind chamber 7 by theevaporators 3, the evaporators 3 dehumidify, cool, or heat the freshair, and therefore functions of the evaporators 3 are fully utilized.

According to the fresh air assembly above, a dehumidifier module isremoved, and fresh air that is to enter an air-conditioned room isprocessed by using the evaporators 3, thereby improving utilization ofthe evaporators 3. In addition, the evaporators 3 are disposed aroundthe cross-flow impeller 2, and this increases the space on the airintake side of the evaporators 3, ensures the intake volume and flowrate of the fresh air, and effectively ensures the volume of fresh airentering the room. Moreover, because the dehumidifier module is removed,noise is reduced, overall energy consumption and costs are decreased,and cleaning and maintenance are more convenient.

Referring to FIG. 1 to FIG. 6, in another embodiment, there are at leasttwo evaporators 3, and the evaporators 3 are sequentially connected andare disposed in the direction around the cross-flow impeller 2.Preferably, there are two evaporators 3, and the two evaporators 3 areconnected to each other to form a V shape. Certainly, there mayalternatively be three evaporators 3, and the three evaporators 3 aresequentially connected. There may alternatively be four evaporators 3,and the four evaporators 3 are sequentially connected in a C-shapedarrangement, and so on. Connecting a plurality of evaporators 3 togetherincreases not only the area of the evaporators 3 but also the spacebetween the evaporators 3 and the housing 1 and the fresh air volume onthe side of the evaporators 3 that faces away from the cross-flowimpeller 2. As such, when a negative pressure is formed on both sides ofthe evaporators 3 under the action of the cross-flow impeller 2, avolume of fresh air drawn into the wind chamber 7 by the evaporators 3from the second cavity 6 increases. This ensures that a sufficientvolume of fresh air flows into the room, and the air-conditioning effectin the room is maintained.

In another embodiment, the evaporators 3 are arc-shaped or semicircular,and the arc-shaped or semicircular evaporators 3 are disposed on oneside of the cross-flow impeller 2 in the direction around the cross-flowimpeller 2. Disposing the arc-shaped or semicircular evaporators 3 tomanufacture the evaporators 3 at a time omits an assembly procedurerequired for using multiple evaporators 3, making the assembly moreconvenient.

Referring to FIG. 4, in another embodiment, the air deflector 4 isprovided with air-guiding holes 4231, and the first cavity 5communicates with the second cavity 6 through the air-guiding holes4231. Directly disposing the air-guiding holes 4231 facilitates flowingof the fresh air from the second cavity 6 to the first cavity 5. In thisembodiment, the air-guiding holes 4231 may be rectangular, circular,triangular, pentagonal, hexagonal, or the like.

In another embodiment, there are at least two air-guiding holes 4231,and the at least two air-guiding holes 4231 are spaced on the airdeflector 4. Disposing a plurality of air-guiding holes 4231 canincrease the volume of fresh air flowing into the second cavity 6,thereby ensuring a sufficient volume of fresh air in the second cavity6. In this way, the evaporators 3 can continuously draw the fresh airfrom the second cavity 6 into the wind chamber 7 and blow the fresh airfrom the wind chamber 7 into the room. Moreover, the plurality ofair-guiding holes 4231 are spaced on the air deflector 4, and this canensure sufficient strength of the air deflector 4, so as to prevent thestructural strength of the air deflector 4 from being reduced becauseonly one air-guiding hole 4231 with a large diameter is disposed toensure the fresh air volume.

Referring to FIG. 1 and FIG. 6, in another embodiment, the housing 1includes a bottom plate 11, a top plate 12, an outer side plate 13, andan intermediate separator plate 14. One end of the outer side plate 13and one end of the intermediate separator plate 14 are respectivelyconnected to opposite ends of the bottom plate 11. The top plate 12 isdisposed at the other end of the intermediate separator plate 14, and isspaced from the other end of the outer side plate 13 to form the airoutlet 17. Preferably, the bottom plate 11 further includes two endplates 15. The two end plates 15 are respectively connected to the twoends of the outer side plate 13, the two ends of the intermediateseparator plate 14, the two ends of the bottom plate 11, and two ends ofthe top plate 12 to form an internal space accommodating the airdeflector 4, the evaporators 3, and the cross-flow impeller 2. In thisembodiment, the air inlet 16 is disposed on the intermediate separatorplate 14.

Referring to FIG. 1 to FIG. 6, the air deflector 4 includes an arcsegment 41 and a bending segment 42. The arc segment 41 is disposed onan outer side of the cross-flow impeller 2 in the direction around thecross-flow impeller 2, and one end of the arc segment 41 is connected tothe top plate 12 and the other end thereof is connected to the bendingsegment 42. The bending segment 42 is fixedly connected to the bottomplate 11. Preferably, the evaporators 3 are fixedly connected to thebending segment 42. In this embodiment, the arc segment 41 can play aflow guiding function, so that the fresh air is blown from the airoutlet 17 into the room along the arc segment 41 under the action of thecross-flow impeller 2. The bending segment 42 is fixedly connected tothe bottom plate 11 to support the arc segment.

Referring to FIG. 1 to FIG. 6, the bending segment 42 includes aconnecting portion 421, an inclined portion 422, a vertical portion 423,and a flat portion 424. One end of the connecting portion 421 isconnected to the arc segment 41, and the other end thereof is connectedto the inclined portion 422. One end of the vertical portion 423 isconnected to the inclined portion 422, the other end thereof isconnected to the flat portion 424, and an included angle between theinclined portion 422 and the vertical portion 423 is an obtuse angle.The flat portion 424 is fixedly connected to the bottom plate 11.Preferably, the evaporators 3 are fixedly connected to the verticalportion 423, and the air-guiding holes 4231 are disposed on the verticalportion 423. The included angle between the inclined portion 422 and thevertical portion 423 is 120° to 160°, preferably 150°. In thisembodiment, the inclined portion 422 is inclined towards a side thatfaces away from the evaporators 3, so that the space of the wind chamber7 can be increased, and the space of the first cavity 5 can be reducedat the same time. This is conducive for fresh air to enter the firstcavity 5 from the air inlet 16 and rapidly flow into the second cavity6.

Referring to FIG. 1 to FIG. 6, a baffle plate 8 is provided between thebending segment 42 and the intermediate separator plate 14. The baffleplate 8 divides the first cavity 5 into an upper cavity 51 and a lowercavity 52. The lower cavity 52 communicates with the air inlet 16 andthe second cavity 6. Disposing the baffle plate 8 can divide the firstcavity 5 into the upper cavity 51 and the lower cavity 52. The uppercavity 51 and the lower cavity 52 are sealed relative to each other, soas to prevent fresh air from entering the upper cavity 51. Afterentering the lower cavity 52 from the air inlet 16, fresh air directlyflows into the second cavity 6 through the air-guiding holes 4231. Thefresh air flows more stably, and this prevents the fresh air fromflowing between the upper cavity 51 and the lower cavity 52 andaffecting the volume of fresh air flowing into the second cavity 6.

In another embodiment, the air inlet 16 is provided with a filterscreen. Disposing the filter screen can prevent dust in the air fromentering into the fresh air assembly, and prevent the dust from coveringthe evaporators 3 and the cross-flow impeller 2 and affecting theservice life of the evaporators 3 and the cross-flow impeller 2.

Referring to FIG. 7, in another embodiment, the air inlet 16 is providedwith a damper 9 on a side facing away from the first cavity 5. Thedisposed damper 9 can close the air inlet 16 when the cross-flowimpeller 2 stops working. This prevents dust from entering into thefirst cavity 5 from the air inlet 16 and keeping the interior of thefresh air assembly clean.

Referring to FIG. 7, the fresh air assembly further includes an openingapparatus. The damper 9 is rotatably disposed on one side of the airinlet 16 through a rotating shaft. The opening apparatus is capable ofdriving the damper 9 to rotate, so that the damper 9 covers the airinlet 16 up or moves away from the air inlet 16. Disposing the openingapparatus facilitates opening and closing of the damper 9.

Referring to FIG. 7 to FIG. 9, the opening apparatus includes a manualswitch 101 and a connecting rod 102. One end of the connecting rod 102is connected to the damper 9 and the other end thereof is connected tothe manual switch 101. The manual switch 101 is capable of driving theconnecting rod 102 to move, so as to control the damper 9 to cover theair inlet 16 up or move away from the air inlet 16. Specifically, themanual switch 101 is disposed on one end plate 15. The connecting rod102 is L-shaped. The damper 9 is provided with a connecting plate 91.One end of the connecting rod 102 is rotationally connected to theconnecting plate 91. The other end thereof is fixedly connected to themanual switch 101 by bypassing the intermediate separator plate 14. Morespecifically, the intermediate separator plate 14 is provided with afixing plate 103. The fixing plate 103 is provided with a guide block104. The guide block 104 has a guide hole 1041. One end of theconnecting rod 102 passes through the guide hole 1041 and isrotationally connected to the connecting plate 91. In this embodiment,the manual switch 101 includes a base 1011 provided with a chute and ashifting block 1012 disposed in the chute. The shifting block 1012 isfixedly connected to the connecting rod 102. Pulling the shifting block1012 moves the shifting block 1012 along the chute. Then, the shiftingblock 1012 drives the connecting rod 102 to move. The movement of theconnecting rod 102 drives the damper 9 to rotate, so that the damper 9covers the air inlet 16 up or moves away from the air inlet 16. A rubbersleeve 105 is sleeved on the connecting rod 102 between the guide hole1041 and the shifting block 1012 in order to avoid excessive abrasion atthe joint between the connecting rod 102, and the intermediate separatorplate 14 and the end plate 15. In a specific embodiment, when the damper9 needs to be opened to allow fresh air to flow into the air inlet 16,the shifting block 1012 is toggled so that the shifting block 1012 movesalong the chute towards a side close to the intermediate separator plate14, and the shifting block 1012 pushes the connecting rod 102 to movealong the guide hole 1041. Then, one end of the connecting rod 102pushes the connecting plate 91 to drive the damper 9 to rotate, so thatthe damper 9 moves away from the air inlet 16 and fresh air can flowfrom the air inlet 16 into the first cavity 5. When the air inlet 16needs to be closed, the shifting block 1012 is toggled so that theshifting block 1012 moves along the chute towards a side away from theintermediate separator plate 14, and the shifting block 1012 drives theconnecting rod 102 to move. Then, the connecting rod 102 moves along theguide hole 1041 to drive the connecting plate 91 to move towards a sideclose to the intermediate separator plate 14, so that the damper 9covers the air inlet 16 up and fresh air stops entering the first cavity5.
